Abstract

The use of bio-fertilizer is increasing along with the awareness of eco-friendly life style. The use of bio-fertilizer give several advantages such as enhancing plant growth, provide plant nutritions, easily absorbed by plant and environmental friendly. Endophytic fungi can be used as biological fertilizers.In this study, endophytic fungi Penicillium citrinum isolate P3.10 were used as a main ingredient for biological fertilizers. This study aims to investigate: (a) the most effective carrier material for biological fertilizers made from endophytic fungi P. citrinum and (b) maximum shelf-life of biofertilizers. Three carrier materials were tested to find out the best carrier as biological fertilizer carriers. Factorial Completely Randomized Design with two factors used in this study with the first factor is the type of carrier material (rice bran, saw dust, and peat soil), and the second factor is storage time (14, 28, 42, 56, dan 70 days).The result of the study and consideration based on the standards of biological fertilizer regulation of the Minister of Agriculture Number 70 / Permentan / SR.140 / 19/2011) showed that of the three tested carriers (rice bran, sawdust, and peat), peat showed the best performance as biofertilizer carrier with the recommend maximum shelf-life is 28 days (5,62 x 105 cfu/gram) due to its C/N ratio value and its viability to maintain the number of viable fungi. Keywords: formulation, biofertilizer, endophytic fungi, peat soil, shelf-life

Abstract

ABSTRACTCashew nut (Anacardium occidentale L.) shell is abundantly available as waste from chasew nut processing industries. Cashew nut shell is potentially used for activated charcoal. This paper characterize the porosity microstructure of activated charcoal made from cashew nut shells which is physically activated at various activation temperatures. Initially, cashew nut shells were collected and carbonized at 500°C for 3 hours. Then, the charcoal was activated at 800°C and 1000°C for 60 minutes. The characterization of microstructure porosity of cashew nut shell activated charcoal at transverse cross-section was carried out at 500 times magnification of 10 kV Scanning Electron Microscope (SEM) using a grain-shaped test sample. Observation of the porosity formed on the sample surface included pore size and frequency. Observation data were arranged in tabulated form and analyzed descriptively. The results showed that the frequency of pores in charcoal activated at 1000°C tended to be higher than that of charcoal activated at 800°C. The higher activation temperature increased the pore diameter of the charcoal and decreased the clogging residue.Keywords: mesoporous, pyrolysis, hydrocarbon
